Seeking advice: how to choose a no-code app platform

Hi friends, I am looking for some advice to help me pick the right no-code platform to build an MVP. I am a non-technical founder and looking to build an MVP as quickly as possible. So I will need one that's easy to work with. In addition, I am hoping to build a calendar sync function in the App. Is it something reasonable to expect from a no-code app platform? Anyone has experience with any and would be interested share thoughts?

Thank you in advance!
